NOTE:
Water that has been treated by the Reverse Osmosis process can become aggressive (due
to lack of minerals or Ions), and in extreme cases can cause leaching and corrosion of pipes,
fittings and other metal parts within the appliance.
If the appliance is being fed by water treated by Reverse Osmosis, we strongly recommend that
the water is tested regularly.
If you have any queries in this respect, please contact our customer services team.
WE REGRET THAT INSTANTA CANNOT BE HELD RESPONSIBLE FOR SCALE RELATED PROBLEMS IF
A SCALE REDUCER HAS BEEN INSTALLED
MAIN UNIT OVERFLOW
A 15mm push-fit overflow connection point is provided [right-hand side of under-counter unit]. This
should be directed to a permanent waste
(see drawing)
. Use pipe-work with a continuous fall,
diameter of pipe to be no less than 15mm. [NOTE: An air gap must be provided within 500mm of
the connection point. Failure to provide an air gap within this distance could cause an air lock
which would stop the water discharging in the event of an overflow].
Failure to connect the overflow-outlet to a permanent waste or drain, could lead to property
damage from flooding.
If in all circumstances, it is absolutely not possible to direct the boiler overflow-outlet to a
permanent waste or drain, then the mains water supply to the boiler should be isolated and the
unit switched off whenever it is left unattended for long periods (e.g. overnight).
IMPORTANT:
Whilst reasonable precaution is taken to prevent an overflow, Instanta cannot be
held responsible for any damage caused as a result of incorrect installation or blockage of the
overflow or failure to direct the overflow to a safe outlet.
FONT OVERFLOW
Drip tray drain kit
–
The drain kit needs to be installed in the drip tray with the kit supplied. When
this is done, the drain pipe needs connecting to a permanent waste. This drain carries any
drips/spillages from the drip tray away.
